WIRE-STRETCH ER.

SPECIFICATION forming part of Letters Patent No. 565,160, dated August 4, 1896.

Application filed December 4, 1895. Serial No. 571,023. (N0 model.)'

To all whom it may concern.-

Be it known that I, MORTIMER EWART, a citizen of the United States, residing at Mogadore, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in \Vire Stretchers and Tensions; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference mark ed thereon, in which- Figure 1 is a View showing a post properly located and illustrating the wire-drums mounted thereon, also showing a portion of the fence-wires and one of the intermediate posts. Fig. 2 is a detached view of awrench designed for rotating the drums. Fig. 3 is a detached view of one of the drums, showing the different parts attached thereto Fig. 4: is a transverse section of the post and drum, showing the tension-spring properly attached.

The present invention has relation to wire stretchers and tensions; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar letters of reference indicate correspending parts in all the figures of the drawlugs.

In the accompanying drawings, A represents the post upon which are to be located the drums and tension-springs and is designed to be located at the end of a fence, or, if desired, a post, such as A, together with its dif ferent parts, may be located at each end of a fence, and when a long fence is to be constructed, posts, such as A, and its different parts may be located at intervals along the fence; but this is simply a matter of jut gment as to the number of posts to be used in the construction of fences.

The post A is preferably formed of metal, and hollow, as illustrated in Fig. 4, and of course is to be placed in an upright position and so held in the ordinary manner. Upon the post A are located the drums B, which drums are arranged substantially as illustrated in Fig. 1. One end of each of the drums B is provided with the angular portion c, which angular portion is for the purpose of rotating the drums upon the post by means of a wrench, such as C; but it will be understood that other forms or wrenches may be used,if desired. To the drums B are attached the ends of the wires 1), and said wires wrapped around the drums, substantially as illustrated in Figs. 1 and 3.

The drums B are each provided with a se ries of apertures, such as c, which apertures are for the purpose of receiving the ends of the springs D, as illustrated in Fig. 4, and thereby hold the drums against rotation. The apertures c are each provided with the inclined faces or shoulders d, which inclined faces or shoulders are for the purpose of permitting the drum to be rotated in one direction and in the direction calculated to tighten the wires. For the purpose of causing one spring D to hold two drums against rotation, the fence-wires b are wound in opposite directions upon each set or pair of drums. Another object and purpose of winding the fencewires around the drums in opposite directions is to have the strain come upon both sides of the fence-post A, thereby causing an even and uniform strain upon the post and drums.

\Vhen it is desired to tighten the wires 7), the drums B are rotated in the direction that will wind the wires upon the drum. As the drums are rotated the inclined faces or shoulders (Z will lift the end of the spring D out of the aperture 0, thereby leaving the drum free to be rotated. As the wires are tightened the spring D will catch the apertures as they are rotated, and when the wire has been sufli-.

ciently tightened said drums will be held against backward rotation by means of the spring engaging one of the apertures, as illustrated in Fig. 4:. It will be understood that by winding the wires in opposite directions upon each of the drums that said drums will have to be rotated in opposite directions to wind the wires and that the ends of the spring will hold against each other. If desired, crosspins, such as 6, may be placed through the post A to hold the drums in proper position. The upper drum B of each set will be held against down ward movement by means of the springs D. It will be understood that the springs D will have the proper amount of tension to allow for the contraction and expansion of the wires B; but when the wires are become slack from long use or any other cause they can be easily and quickly tightened.

The ordinary posts E are provided with staples f, which staples hold the fence-Wire.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of the post A, having mounted thereon the drums B, said drums being provided with the angular ends a, and the apertures 0, located upon the peripheries of the drums and provided with the inclined faces or shoulders d the springs D, located around the post A, and engaging the apertures c, and the fence-wires I), wound in opposite directions upon each set or pair of MORTIMER EWART.
